Do you know what is youtube video thumbnail? what is thumbnail resolution size? what is thumbnail aspect ratio? what is maximum thumbnail size in MB? Best thumbnail formats are...?

Video thumbnails let viewers see a quick snapshot of your video as they're browsing YouTube. After your video is finished uploading, you can choose a thumbnail from the three options YouTube automatically generates, or upload your own.

Your custom thumbnail image should be as large as possible. It will be used as the preview image in the embedded player.

Your custom thumbnails have a resolution of 1280x720 (with minimum width of 640 pixels).
Be uploaded in image formats such as JPG, GIF, or PNG.
Remain under the 2MB limit.
Try to use a 16:9 aspect ratio as it's the most used in YouTube players and previews.
